(Cl. l01126) 14 Claims.

This invention relates to apparatus for applying designs upon flexible webs of textile fabrics. Paper. and like materials, and more particularly to an improved apparatus employing a stencilprinting screen. v

This invention is an improvement over a screen printing apparatus disclosed in a prior Patent No. 2,210,474. issued August 6, 1940, to George H. Tillett, entitled "Color printing web."

This application is a continuation of our prior application, Ser. No. 364,604, filed November 7, 1940, entitled "Screen printing apparatus.

One object of this invention is to provide an improved form oi of color squeegee for spreading the color paste upon and through the stencil screen and means to support the same out of contact with said screen at the rear end of its stroke.

A further object of this invention is to provide an improved apparatus for applying designs upon flexible webs of the above nature. which will be relatively inexpensive to manufacture, simple in construction, easy to operate by relatively unskilled labor, compact. ornamental in appearance, and very eflicient and durable in use.

With these and other objects in view, which will appear as the description proceeds. there have been illustrated in the accompanying drawings several forms in which the invention may be conveniently embodied in practice.

Briefly, the screen printing apparatus of this invention includes a central table for supporting a screen frame and a pair of spools, one carrying a roll of web to be printed, and

is wound in spiral condition, the color paste fresh- 1y printed upon the web will be kept out of contact with the adjacent layer of said web, whereby smudging of said color will be prevented, and said iresh color will be given a chance to dry. The spacer strips also serve to separate the successive In the drawings:

Figure 1 is a front elevational view of an improved screen printing apparatus embodying the invention.

Flgure 2 is a broken end elevational view of the the other serving as a take-up roll for the web after printing. The

layers of the web and provide between them a draining space through which a stream of dry air mayberorced.

B winding the printed web in spiral form upon the take-up spools, the material may be stored while drying or curing in the minimum of space as compared to the former methods of drying printed webs on elongated flat tables or suspending said webs in festoons or loops.

Figure 3 is a top plan view of the same.

Figure 4 is an enlarged broken horizontal view of the upper part of the machine taken on the line H of; Figure 3.

Figure 5 is a view similar to Figure 4, but show. ing the stencil screen with one end raised from the web to be printed, and with the squeegee also raised and supported out of operative position.

Figure 6 is a perspective view of the squeegee and its holding and operating frame.

Figure 7 is a perspective view of the squeegee shown by itself.

Figure 8 is a sectional view of a modified form of the invention having a spring-pressed adj stable spool flange. Figure 9 is an end view of the same.

Referring now to the drawings wherein like reference numerals designate like parts throughout the several views, the numeral I0 denotes a flat table top which, in this instance. is suitably supported by four corner uprights, or legs II, i2, i3, and It. The uprights ii and I2 are connected and braced by horizontal bars l5, l6, and I1, while the uprights l2 and. I are likewise connected and braced by similar horizontal bars located behind said bars I 5, i6, and I1, and concealed thereby as viewed in Figure 1. The front uprights l 2 and II are connected andv braced at the top1by hori-.

zontal side bars i8, is, and 20, and the uprights II and I4 are braced by similar sidebars concealed thereby. At each end of the apparatus, provision is made of upright bars 2i extending from-the lower horizontal bar l5 tothe upper bar l1, and a short vertical-bar 22 extends at'each side from the intermediate horizontal bar I! to the lower bar 20 (Figure 2).

Provision is also made of a pair of horizontal shafts 22 mounted in and extending between the uprights Ii and I2, and the uprights i4 and I3. respectively. Each of said shafts 23 is journaled at each upright ll, I2, ll, and II, in brackets 24 (Figures 1 and 2), each of which is vertically ad- Justable in and is secured to the respective upright by a bolt 28 passing through an elongated slot 28 provided in the bracket 2 and screwthreaded into the respective upright. A hand wheel 21 is secured on the front end of each shaft flandasprocketllissecuredontherearend 66 of said shaft. The shaits 22 are extended at 7 mg operated;

their" frontends a beyond the uprights n and bracket and through the table top extension at (Figures2and3). Ananglepiecei'lsecuredto the table top extension I! has"; screw 99 threaded therethrough into engagement with each of the brackets 92 and 99 to permit them tobe held in any desired position and to prevent said bracketsfrom moving rearwardly when the machine is be- Stencil screen Provision is also made of aswingable stencilsupporting frame (Figures 1 to 5), comprising end rods 99 and 49, and side bars 4| and 42, the rear end rod 49 being pivoted in bearings 43 and 44 I carried by the brackets 32 and 99 respectively. The rods 39, 49, 4|, and 42 are connected together at the corners of the stencil frame by four angle blocks 49, thus maintaining the frame in rectangular shape. I v

Four vertically disposed posts 49 extend upwardLv--one from each angle block 49to supi port side rods or tracks, 41 and 49, which are spaced above the side rods 4| and 42 respectively, and are parallel thereto. ,An elongated angle bar 49 extends between the side rods 4| and 42 adjacent the front end of the screen-supporting frame, and a similar. angle bar 59 extends between the rods 4| and 42 adjacent the rear ends there-' of. The angle bars 49 and 59 are adiustably secared to the respective rods 4| and 42 by clamping brackets II, and are arranged to have one of their angle portions horizontal and theother vertical. By means of the brackets 5 l the angle bars 49 and 99 may be adjusted'longitudinally in the direction a of web travel along the rods 4| and 42 to position the stencil frame supported thereby in the desired location.

The horizontal base portions 92 of the angle bars 49 and 99 extend toward each other and form oppo in seats for a rectangular stencil screen, which, in this instance, is made of four narrow wooden strips 53, i4, 95, and 99, and secured together at their adjoining ends. A printing stencil sheet 91 is stretched across the bottom of thestencil screen, said sheet 51 being preferably made horizontal portions 52 of the angle bars 49 and 99 of the swingable stencil screen supporting frame. The stencil frame, comprising the strips 99, I4, 99, and 99, is seated in the carrying frame, comprising the bars 99, 49, 4|, and 42, and maybe I brought into exact register-with the design on the stencil screen by adjustment of the vertical limit arm 99 (see Figures 2 and 3), of an adjustable "guide bar having a'horizontal arm 99 which is secured to the table top II by bolts 99 and II which pass through elongated slots 92 and I9 respectively, provided in the horizontal arm 99, and which bolts are screw-threaded into the table top l9. The stencil frame is definitely located at its front the screw head 1|.

end'by a slidable block 94, adapted to be clamped adjustably to the angle bar 49 by a thumb screw 99, and an angle strip 99, secured to the stencil frame strip 93 by screws 91, one arm 99 of said angle strip being adapted to engage the block 94.

Lengthwise adjustment of the stencil frame is obtained by the use of a pair of transversely spaced apart wood screws 99 and 19 (see Figures 3 rearleg ll thereof provided with a slot I4 extending upwardly from its lower edge and adapted to embrace the respective screw 99, 19 therein with A thumb screw 19 is screwthreaded through the front leg 19 of the U-shaped block 12 and engages a loose clamp plate 'I'I for engaging the vertical portion of the angle bar 49 to securely clamp the front stencil frame strip 99 thereto. By manually rotating the screws 99 and 19 by means of a suitable tool, such as a screw driver, before clamping them to the bar 49, by the block 12, adjustment of the stencil frame may be made to compensate for any possible warping thereof. The rear strip 95 of the stencil frame may be detachably secured to the angle bar 99 in any suitable manner, but is herein shown as being merely seated therein (Figures 4 and 5), with its rear edge abutting the vertical portion 19 of said angle bar 99. I

By means of the above structure, it will be seen that the stencil frame is adjustable transversely and lengthwise upon it carrying frame and that variations in width of different stencil frames may be compensated for by adJustment of the vertical limit arm 59 and the adjustable block 94. Variations in the length of different stencil frames is compensated for either by means of the adjustand 'II, or both.

The stencil screen 99, 54, 55, and 99, may be manually lifted from the underlying web W whenever it is desired to shift the web, by swinging treadle 99 which, as shown in Figure 2, is connected to the front rod 99 of the screen carrying frame through a system of links and levers arranged with a "mechanical disadvantage" whereby a comparatively small movement of the treadle 99 will move said frame a relatively large amount.

The foot treadle 99 is pivoted at 9| to a cross bar 92 extending between the lower side bars 29, and provision is made of a short upstanding link 99, which loosely connects the forward part of the treadle 99 with a long vertical link 94. The upper end of the long link 94 is loosely connected to a. short vertical link 95, which in turn is pivoted to an inclined arm 99 at a point closely adjacent the lower fixed end 91 thereof. The end 91 of the arm 99 is pivoted to the front intermediate upright 2| between a pair of angle blocks, and the upper end 99 of the arm 99 is connected by a chain, 9| (see Figure 2), reeved over a pulley 92, supported on of the printing apparatus to the other.

04, which is adapted to loosely embrace the upright 2|.

The slide 04 is connected tothe lower end of an upstanding plate 05 (Figures 2 and 3) which carries a short horizontal shaft at its upper end.

The shaft 05 extends beyond the sides of the plate 05 and has rollers 01 iournaled on each end thereof. The rollers 01 engage blocks "secured to the underside of the front screen frame rod and serve to reduce friction. B means of this construction, it will be seen that, when the operator steps on the treadle 00, force will be transmitted through the links 03, 04, 05, arm 00, chain 0|, slide 04, plate 05, to the rollers 01, causing the front end of the stencil screen carrying frame to swing upwardly and lift the stencil screen out of contact with the web W. To assist the operator in this operation, counterweights 90 may be hung upon the arm 00 adjacent its u p r end 00. The stencil carrying frame is engaged at its forward end by a pair of curved strips I54 and I55 (see Figures 1 and 3) which serve to guide the angle blocks 45 as this frame is lowered into place.

The web W is adapted to be fed across the table top I0 under the stencil screen 51 from one side In order to avoid any stretching or movement of the web W, it is temporarily secured upon a carrier band,

or belt, I00, preferably constructed of heavy flexible paper, by means of a non-drying, sticky ad- .hesive which may be composed, for example, of a mixture'of china clay and glycerine. By the use of this adhesive, the carrier belt I00, may be used repeatedly before replacement is necessary, due to the fact that it may be stripp d therefrom re- Deatedly without damage to the belt I00 or the web W. In most instances only the outer fibres at the undersurface of the web W are impregnated by the adhesive.

Provision is also made of a pair of spacer strips IN and I02 disposed beneath both margins of the carrier belt I00, and preferably cemented thereto. It will be understood that said strips III and I02 may, if desired, be riveted to the carrier belt I00 as by eyelets, within the scope of the invention. The combined web W, carrier belt I00, and spacer strips IN and I02, are adapted to be guided across the table top I0, by means of a pair of-transverse grooves I03 and I04, respectively, formed in the upper surface of said table top I0 (Figures 4 and 5) When the web W and the carrier strip I00 are wound into a spiral coil upon a spool I05 (as shown in Figures 1 and 2), it will be understood that the belt I00 will be spaced apart in successive layers by the strips MI and I02 at its edges, thus providing an air space therebetween, protecting the color paste printed on the web W and preventing "smudging of the table top I0 thereby. The color will thus be permitted to penetrate uniformly into the web and produce a sharp and distinct reproduction of the design thereon The edges of the web carrier belt I00 outside theweb are preferably coated with shellac or other suitable material to seal them against moisture and afford additional stiflening.

The color paste employed in the screen printing apparatus is adapted to be forced through perforations in the stencil screen 51 onto and into the web W by means of a squeegee blade I00 (Figures 2, 4, and 5), preferably made of soft rubber and having its upper edge set into a recessed strip I01. The strip I01 ishinged as at I00 to another strip I00, located above it, which strip I00 is adapted to be clamped between a pair of transverse angle barsilland III by a pair of thumb screws H2. The angle bars Ill'and III are secured to the forward ends of a pair of short horizontal slide members I I2 and Ill of inverted U-shape in cross-section. The legs of each inverted U-shaped member straddle the parallel side tracks 41 and 40 and thus guide the squeegee blade I" in its manual reciprocation by the operator who grasps a relativel long handle rod III secured at one end to the cross bars II. and

10 III, as shown in Figures 1, 2, 3, 4 and 5. It will be noted that the inverted U-shaped guiding members Ill and H4 do not actually rest on the tracks 41 and 40, but the weight of this structure and the squeegee blade I05 is imposed directly upon the stencil screen" so as to cause the color paste to pass therethrough and upon the web beneath it. The pressure of the squeegee blade I00 upon the screen ma be increased if desired by the use of suitable ring shaped weights III) surrounding a pair of vertical posts II1 extending upwardly from the guide members II4.

In operation, the squeegee blade I00 will be lifted at each end of its stroke and moved and lowered at the opposite side of the mass of color paste so as to push it in the reverse direction.

This operation is readily accomplished by swinging the handle rod II5 upwardly and causing the rear ends H0 and I20 of the guide members Ill and I I4 to engage the tracks 41 and 40 which act as fulcrums therefor.

When the printing operation-is completed, the squeegee blade I00 will be raised away from the stencil screen 51 and maintained in such raised position, while the stencil screen is also lifted and the web shifted to bring a new unprinted portion into registry with the screen. For this purpose, provision is made of a pair of transversely spaced apart standards I2I and I22 (see Figure 3), secured to the table top I0 to the rear 40 ofthe stencil screen supporting angle bar (see Figures 3, 4, and 5). Each of the standards I2I and I22 has a horizontal rearwardly extending arm I20, I24, and a forwardly extending angle arm I25, I25, respectively. The arms I 20 and I24 extend outwardly in opposite directions and carry rollers I21, and the arms I25 and I20 extend inwardly toward each other and carry rollers I20 (see Figures 2, 3, 4, and 5) When it is desired to support the squeegee blade 0 up out of contact with the stencil screen 51 at the rear end of its stroke, it will merely be necessary to tilt the handle II5 upwardly to cause the rear ends [I0 and I20 of the guide members Ill and I I4 to be disposed under the rollers I21, and the rear cross bar III to be disposed above the rollers I20 (as shown in Figure 5). The webcarrying belt with the web W adhering thereto may then be fed across the table top II from the feed spool I05 on one side of the printing apparatus to the take-up spool I05 on the other side. Each of the spools I05 has a hollow shaft I29 which extends from its rear end, and has a sprocket I00 detachably secured to said extending end by a set screw III, A chain, I42,

is reeved over the sprocket Ill and the sprocket 20 on the hand wheel shafts 25 whereby rotation of the hand wheel 21 on the take-up side of the apparatus will cause the web W to be fed across the table top II from the feed spool I05.

when in alignment indicate to the operator that Spools As herein shown, a pair of identical spools IIII, are provided which may be selectively used for "feeding" and takingp of the web. Each spool is permanently mounted upon a truck I" having casters I whereby it may be wheeled toward and away from the apparatus to carry the web into and out of printing position. In order to insure accurate registration of the printed designs on the web, means are herein provided on each side of the printing apparatus for alining the spool carrying truck I" with said apparatus. The positioning means above referred to includes two pairs of resilient arms I21, I21a extending outwardly from the corner uprights I2, I8, and II, II. The arms I21, Illa are each curved outwardly to facilitate the movement of the side base bars I30 and I" of the truck I" into engagement therewith and to guide the feeding spool so that the web W to be printed will be in correct transverse registry with the stencil screen when it is fed into printing position.

In order to lock the spool truck III in operating position, provision is made on each of said positioning means of a toggle mechanism comprising a lever I40 having one end pivoted as at III to the adjacent resilient arm I31, "1a. A handle I42 at the other end of the lever I40 is provided to manipulate the same. Provision is also made of a thin rod I having a hooked end I adapted to catch into an elongated slot I provided in the side base bars I 20 and Ill and pivotally secured to the lever I40 intermediate its ends. said rod in passing through a vertical post I which is arranged to rotate in the lever I. A coiled spring I41 surrounds the rod I48 and reacts between the post I" and a washer held on the outer end of the rod Ill by lock nuts I" and I00. When it is desired to hold the truck in locked position, the hooked end I of them I will be connected to the truck side bars I00 and I" by engagement in the slot I45 nearest thereto and the levers I40 will be swung into the truck-locking position. If desired, an additional slot I may be used so that the trucks may be readily reversed and either side thereof selectively applied to the printing apparatus.

Web-drying apparatus While the apparatus is being operated, and a freshly printed web W is being wound continually upon the take-up spool I05, a constant flow of dry air will be directed against the surface of the web on said spool by means of a duct IOI leading from a central motor driven air blower I52 (see Figure 1). Additional drying may also be obtained by means of an auxiliary blower, not shown, to force dry air into the hollow spool shaft I20, which air will be caused to flow outwardly through perforations I83 therein and between the layers of the spiral coil of web W wound thereon.

In the modified form of the invention shown in Figures 8 and 9, a cross rod I14 is secured to the table III by a pair of brackets l1la, "la. 'The cross rod I14 is provided with a pair of spaced collars I15 and I16,for supporting the interior ofthe carrier belt I00 as it passes from the spool to the top of the table I0.

Provision is also made of an adjustable flanged guide sleeve I11 having a large flange "1:: which is mounted to slide on one end of said cross rod I14 and is pressed inwardly at all times by a coiled spring I10 reacting between a pair of small flanges I10 I00 formed on said sleeve I11 and said cross rod I14, respectively An adjustableilanged sleeve IIlI is'mounted on theopposiie end of the cross rod I10 and may be held in any desired position by a set screw I02.

The above construction will be used when the spacer strips are not secured to the carrier belt, or should become accidentally separated therefrom.

Operation The operation of the above described screen printing apparatus is substantially in accordance with that disclosed in the above-mentioned Patent No. 2,210,474. In brief, the operation is as follows: I

Assuming the squeegee blades I06 is held in raised position by the rollers I21 and I28 (see Figure 5) the stencil screen frame will be swung upwardly by depressing the treadle 80. The webcarrying belt I00 will be drawn across the table top I0 from the feeding spool I05 with the spacer strips Ill and I02 guided by the grooves I03 and I04, respectively. The free end of the web-carrying belt I00 will-then be attached to a take-up roll I05, which has first been blocked in place at the other side of the printing apparatus, by threading it through the slot I12 in a longitudinal bar I13 of the take-up spool. The hand wheels 21 will then be turned to bring the first mark I33 on the carrier belt into alignment with the mark I34 on the table top I0, whereupon the stencil screen holdin frame will be lowered to cause said screen to engage the web W. The squeegee blade I06 will then be lowered upon the rear end of the stencil screen 51 and the proper quantity of color paste will then be placed upon the screen 51 in front of the blade I06, which may then be pulled forwardly by means of the handle H5. I

When the squeegee blade I06 is in its forward position after having traversed the length of the screen 51, it will be lifted by tilting the handle IIS upwardly and placed in front of the mass of color paste, and then pushed rearwardly to spread the same along the screen 51. After the desired number of strokes of the squeegee blade I06 have been made, said blade will be latched in its raised position as above described. The stencil carrying frame will be swung upwardly by means of the treadle 80. The web W will then be fed along the desired amount to bring the next desired indicating mark I33 on the web-carrying belt into registry with th mark I34 on the table top I0. This procedure will be continued until the web has been completely unrolied from the feed spool, and wound up on the take-up spool.

After the spool of unstenciled web has been unwound from the feeding spool, printed, and wound up on the take-up spool, the latter maybe unlocked and rolled away from the printing apparatus for drying or other treatment. It will then be returned to the printing apparatus on either side thereof, if desired, and the previous takeup roll will then serve as the feed roll-it being merely necessary to shift the crank handle 30 to the other shaft 23 to operate the feeding mechanism and take-up mechanism, as described above.

While there has been disclosed in this speciflcation several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that th invention is not to be limited to the specific disclosures, but may be modified and embodied in various other forms without departing from its spirit. In short. the invention includes all the modifications and embodiments coming within the scope of the follow- ,inlclaims.

a chain connected to said plate, and passingaround a pulley connection to a lever, and linkage means to connect said lever to said treadle, whereby depression of the latter will raise said frame to carry said stencil frame upwardly and permit said web to be advanced thereunder to its next printing position.
